17. This slab holds an array of different types of footprints including those from (Choose any that  are correct/apply ): a nodosaur adult and baby, a long-necked Sauropod, some crow-sized  carnivorous dinosaurs closely related to the Velociraptor,  some Pterosaurs 18. Perhaps the mammals were feeding on worms and grubs, the small carnivorous dinosaurs  were after the mammals, and the  pterosaurs could have been hunting both the mammals and  the small dinosaurs. 19. What suggests that the four crow-sized carnivorous dinosaurs were hunting or foraging as a  group? "It looks as if they were making a sweep across the area," Lockley said.  The four  trackways are parallel to each other. 20.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
